What Does Relative Humidity Mean?
Relative humidity is a measure of the amount of water vapor present in the air. It is expressed in the form of a percentage of the amount of water needed for saturation at the same temperature. It is also the ratio of water vapor’s partial pressure to the equilibrium vapor pressure of water at a given temperature.
It is important to not let relative humidity cross 100 per cent for aeroponics because the water vapor in the air begins to condense and form droplets. To optimize the nutrient intake of plants grown in an aeroponics system, it is necessary to moisten the roots just right to the point where it is damp and water isn’t dripping.
